IMPROVEMENT IN ROLLING-M ILLS.

Specification forming part of Letters Patent No. 219,833, datedSeptember 23,1879; application filed May 19, 1879.

To all whom it may concern:

Be it known that I, STEPHEN P. M. TASKER, of the city and county ofPhiladelphia, in the State of Pennsylvania, have invented a new anduseful Improvement in Continuous Rollin g-Mills for Rollin g and EdgingFlat Metal, of which the following is a full, clear, and truedescription, reference being had to the accompanying drawings, formingpart of this specification, in which- Figure 1 is a central horizontalsection, viewed from above, of so much of myimprovedmachine as isnecessary toillustrate its practical construction in the plane of thefeed, andbetween therolls AA Fig. 2, acentral longitudinal verticalsectional elevation of the same portion of the machine, in a verticalplane between the'vertical rolls; Fig. 3, a cross-section of one form ofshaper or die; and Fig. 4, cross-sections of forms of sheets, plates, orbars produced by the use of my machine; Fig. 5, a view similar to Fig.2, the shapers being omitted; and Figs. 6, 7, 8, and 9, sectional viewsof various forms of shapers.

My improvement relates to rolls for flat-rolling, and more especially tothat subdivision of the same which both roll the flat surfaces and shapethe edges of the product acted upon.

The object of my invention is to produce flat sheets, bars, strips, orplates of metal, the edgesof which are shaped to any desiredconfigurationas, for example, to such forms as are represented in Fig.4. in the drawings.

In the drawings, I have represented so much of a construction of machineembodyingmy invention as is necessary to. a comprehension of the saidinvention.

In the drawings, A A represent a pair of plain-faced horizontal rollsmounted in a suitable housing, B; O G, a pair of vertical rolls, alsomounted in a suitable housing, D. E E are two circular-flanged collars,fitted, in the arrangement represented, to the two vertical rolls, andadapted to be secured at any desired point thereon by means ofset-screws F F or similar devices. These collars may be constructed ofany desired form, that represented consisting of a neck portion, ff, towhich the set-screws are applied, and a flange or head, 0 0, being aconvenient form.

The opposing surfaces 9 g of the collars are flat and true with theopposing inner faces h h of the guides, and are to be set insuch manneras to be correspondent with the said inner faces, whatever may be thesize of the guides, so that, by the combined arrangement of the guideand the collars, a continuous inclosed passage-way is formed, thecollars aiding to hold the sheet in place in its transit, and to preventthe metal from spreading while the edges are being rolled, serving alsoto aid in carrying the sheet along andin preventing its buckling.

G G is a shaper, edge-die, or former, fitted to likewise encircle thevertical rolls, and adapted to be held between the collars E E so as tobecome fixed in position, as indicated in Fig. 2. In diameter the shaperis less than the collars, so as to be overlapped by. both col lars,which are of greater diameter, and which, as explained, form a portionof the inclosed way through which the sheet is caused to pass. Each ofthe vertical rolls, Figs. 1 and 2, is similarly equipped with collarsand shapers.

In Fig. 3is represented, in section, the shaper G. (Shown in Fig. 2 inside elevation.) The function of these shapers is the shapingof the edgeof the sheet to a form corresponding .with that of the shapers, whateverthe same may be.

H is a guide for conducting the metal to be rolled from and between thevarious pairs of rolls.

Several sets of rolls may be used in series, in which arrangement theguides are employed between each set.

The form of guide represented is funnel shaped or bell-mouthed at itsreceiving end, inclosed or box-like, and of a construction andarrangement employed by me for many years.

In the arrangement represented the collars do not touch, but a smallspace is left between them, into or near which the discharging end ofthe guide Hproj ects. The sides of the guides are cut away, tocorrespond with andmergeinto the periphery of the collars E \E, whilethe top and bottom of the guides coincide, as described, as to theirinside faces, with the opposing faces of the collars, so as to form acontinuous in closed pass or way.

When desired, the collars can be made to touch together, and the guideshaped to correspond. When the rolls are arranged in series, eachsucceeding guide is fuimel-mouthed, and preferably arranged asrepresented in Fig. 1.

The shapers maybe of any form desired, so as to form any givenconfiguration on the edge of the sheets or plate.

In the operation of my machine, the sheet metal, being first passedbetween the rolls A A, is by them rolled out upon its flat surfaces,caused to enter the guide H, and from thence caused to travel betweenthe vertical rolls, and to pass between the flanges of the collars E E,which form a continuation of the guide, so to speak, and in such manneris brought into contact with the shapers (l, and thereby fashioned uponits edges to a form corresponding to that of the shapers employed.

It is obvious that different forms of dies or shapers may be employed,and that the form of the same may be predetermined to the resultantshape desired.

When it is sought to roll a plain square edge on one side of the metal,the shaper on such side is dispensed with, and the metal shaped upon itsed e by the body of the vertical roll; and, when esired, the shapers maybe all dispensed with, and the collars alone employed, the verticalrolls acting upon the sides of the sheet to true such sides.

The apparatus can, of course, be adjusted to any desired thickness ordimension of plate by varying the adjustment of the rolls, the size andinterior dimension of the guides, the width and diameter of the shapers,and the consequent distance apart and adjustment of the collars.

It is, however, essential that in any adjustment of parts thediameterot'the shaper should be less than that of the embracing-collars.

Instead of making both collars on each roll adjustable, one may befixed.

The adjustability ot' the collars renders the rolls to which they areapplied susceptible of use with varying sizes of sheets, and effectuatesthe practical making of an adjustable pass or rolling groove, while theemployment of shapers still further adds to their efficiency.

It will be understood that the shapers may be dispensed with at will, asrepresented in Fig. 5, either as to any given shaper, or as to any givenseries of shapers, acting upon a given side of the sheet under processof rolling, or as to all, and the rolls employed with the adjustablecollars only.

The guides may be made adjustable, or different sets may be employed.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- In an apparatus for rolling andedging sheet metal, consisting, essentially, of a pair of horizontalrolls and a pair of vertical rolls arranged in alternate series,suitably mounted and driven and united by an inclosed guide or way, thecombination, with the vertical rolls and with the guide, of twoadjustable collars upon each vertical roll, subtautially in the mannershown and described, and for the purpose specified.

In testimony whereofI have hereunto signed my name this 15th day of May,A. l). 1879.
